The first example of a nonbridging η2-coordination of a tetrazolato ligand to a d-block element (Zr) is reported. Three related dinuclear 5-phenyltetrazolato complexes of Ti, Zr, and Ta are structurally characterized.

A tetrazolate- and cyanide-bridged CuII–CoIII bimetallic coordination polymer is the first example of a trinodal (6,8,8)-connected three-dimensional network and is constructed from anionic [Co(CN)6]3− and cationic [(Cu1)2(tta)2]2+ and [(Cu2Cu3)(tta)3]+ units. A magnetic investigation shows antiferromagnetic interactions between the paramagnetic CuII ions.

In the centrosymmetric title complex, [Cu(C6H5N6)2], the CuII ion is coordinated by four N atoms from two symmetry-related bidentate 5-(2-amino-3-pyridyl)tetrazolate ligands in a slightly distorted square-planar environment. There are weak intramolecular N—H
N hydrogen bonds between the two ligands. In the crystal structure, there are significant π–π stacking interactions between symmetry-related tetrazole and pyridine rings, with a centroid–centroid distance of 3.6025 (18)°.

The title compound, [Cu(C5H3N6)2(H2O)2]·2C5H3N3, is a 1:2 co-crystal between the mononuclear complex diaquabis[5-(pyrazin-2-yl)tetrazolato]copper(II) and the reagent pyrazine-2-carbonitrile which was used in the synthesis. The CuII atom is located on an inversion centre and has a distorted octahedral [4 + 2]-coordination environment formed by four N atoms of two chelating bidentate 5-(pyrazin-2-yl)tetrazolate ligands at shorter distances and two water O atoms at longer distances. The CuII complex molecules are held together by O—HN hydrogen bonds and π–π stacking interactions [centroid–centroid distance 3.6139 (8) Å], forming layers parallel to (100). These layers alternate with layers of pyrazine-2-carbonitrile molecules and both are held together via C—HN hydrogen bonds and further π–π stacking interactions.

The title complex, [Ni(C2H1N9)(C10H8N2)2]·6H2O, was prepared under hydrothermal reaction conditions. The asymmetric unit contains the nickel complex and six solvent water molecules. The NiII ion is coordinated in a distorted octahedral geometry defined by four N atoms from two 2,2′-bipyridine ligands and two N atoms from the 5,5′-iminobis(tetrazolate) (BTA2−) anions. In the crystal structure, an extensive range of O—HN and O—HO hydrogen bonds links the complex and the water molecules into a three-dimensional network.
